Action potential refers to an event in which the potential of the membrane of a cell initially increases and then decreases. It is an characteristic characteristic that is present in a wide variety of living cells, including muscles, neurons, and the endocrine cell. Some plant cells also produce them. Neurons play a significant role in cell-tocell communication. Beta cells of the pancreas action potential is linked to hormone release. Plasma membrane is a type of ion channels that are voltage-gated for producing action potential. The channels are closed at times when membrane potential is close to that of the cell . However in the event that the membrane potential grows and the channels begin to open, they become active. If the channels are open, they allow an inward flow sodium ions, which boosts cell membrane power. The swift inward flow of sodium ions can alter the membrane's polarity and , as a consequence, they become inactive. The potassium channels after that are activated and it is a flow potassium ions . The result is that the membrane returns to its neutral state. The transient negative change known as refractory period blocks back forward motion of an action potential. In animal cells , usually two types of potentials are identified, for instance, one which is triggered from voltage-gated potassium channels and the other which can be produced by calcium channels that are voltage-gated.

Nearly all cells maintain in a voltage differential between their outside and indoor environment. The cell's voltage is measured in milli volts (mV). The voltage of a typical animal cell is around -70 mV. For the vast majority of cells, no voltage fluctuations are known for their existence, but in some cells this is a typical characteristic. Certain cells can also exhibit an up-and-down cycle as the voltage drops and increases. The duration of these potentials differ across a broad range. In brain cells, the up and down process of action possible are completed in less than a thousandth of a second. However, in different types of cells, the cycles may take several seconds. The electrical ability of a cell in the animal kingdom is dependent on its membrane structure. Cell membrane is made up of an outer layer of lipids as well as proteins. The lipid layer acts as an insulation.

All animal cells are electro-polarized. They keep a voltage difference known as membrane potential. For the neurons, dendrites and the cell body possess different electrical characteristics. The most stimulated part of an neuron is its axon hillock but axon and cell body are also excited. The axon hillock's resting potential is -70mV and the threshold voltage is 55 millivolts. Synaptic messages to the brain trigger depolarization which causes the membrane potential to rise or decrease. Action potential is created when enough depolarization happens and the membrane current reaches an upper limit.

Action potential is the outcome in the function of voltage-gated channels that are found in the plasma membranes of cells. The voltage-gated channel is actually a group of proteins , which are encased in plasma membranes and generates actions potential due to the fact that it could give rise to a positive feedback loop. Membrane voltage is responsible for managing the state of ion channels. Action potential is generated when the positive feedback cycle takes place at full intensity. The frequency and duration are controlled by the bio-physical characteristics of the ion channels with voltage-gated voltage. Many kinds of ionchannels are known to produce positive feedback cycles that eventually result in the production of these potentials. The sodium channels with voltage are involved in the generation of higher-frequency possibles that resemble those produced by nerve impulses. The slower ones, like those generated by muscle cells are mediated by calcium ion channels.The most thoroughly studied voltage-gated Ion channels are the sodium ion channels that are involved in faster nerve impulse conduction.
